On the next day after the treatment, the cucumberwas sprayed and inoculated with a zoosporangia suspension of fungi ofcucumber downy mildew, and the cucumber was kept in a moist chamber at20° C. for 18 hours. Then, it was kept in a constant temperature chamberof 20° C. for from 6 to 7 days, and the average area of lesions on thefirst leaves of the two seedlings was examined to find the incidenceaccording to the following formula. Here, the average area of lesions inthe non-treated plot was obtained in the same manner as the treatedplot, except that the cucumber was sprayed with water instead of thedrug solution by a spray gun. The results are shown in Tables 1 to 4.
